I use these shoes for running only, on a combination of dirt running trail and road. I am very picky about fit (can't stand long, wide "clown shoe" fit, and can't tolerate any tightness or pressure in the toes). I am a size 8.5 in most shoes (running and other). I bought these in an 8, based on how the first generation Glide fits me, and the fit is perfect. I find the toe box wider than most Nikes (a PRO for me). The length is just right, with just a little bit of extra space--but not a whole extra inch.

So if I bought my running shoes with that added one inch in the toe (which is usually recommended), I would call these true to size (and would be wearing 8.5).

I cannot imagine going a half size up to a 9.

These are very comfortable. Nice cushioning. I've gone on several 6 mile runs in them. No "breaking in" necessary. No rubbing, no blisters.

They feel stable, but they do not have a "built up" structured feeling. I would not recommend these to people who like to feel the arch structure of a shoe when they run.

I also like the very simple style and color. These are not "look-at-me" shoes. That's also a PRO for me. However, it would be nice if Nike added some newer features, or a cool lacing system.

I have purchased numerous incarnations of this shoe over the years. In the past, this style, though very comfortable, lacked durability. I think they finally got it right. The stays across the toe are in the right place to prevent the shoe from wearing out too quickly. The mesh is a also more sturdy, but durable.

I did my research for the appropriate running shoe (learned the hard way from my previous pair of running shoes). I'm still a "novice runner", but looking to improve my overall performance - it certainly helps to have a good running shoe.

I should have purchased two pairs; this is their older version of this shoe, and the newer version customer reviews have been mixed.

I just ordered pairs 5 & 6 of this shoe...I debated ordering a 7th pair, but that seemed crazy. I love these shoes. I run 3-4 times a week, training for half and full marathons and these shoes have not let me down yet. I will be crushed if I can not find them again. I have tried many different pair, but I keep coming back to these shoes.

I constantly track between 35-40 miles a week and these shoes are awesome. I have a slightly wider foot but because of the way Nike built the Vomero I don't have to go up to a wide. I have bought the newer version of the Vomero over the past three years and probably have gone through about ten to twelve of them depending on how good I am about replacing them. But yes ladies, I am that stuck on them.

I bought these sneakers because they were an Editor's Choice in "Runner's World" and they really lived up to the review in the magazine. I love them! The only thing I would change is they are mostly white, so when I wear with jeans I don't feel they look as stylish as other Nike's I have owned. But these were bought for function with fitness, not to wear with jeans. So not a reason not to buy them.

I am an average runner; my runs are on all surfaces and varying distances. I have worn the Nike Triax series for several years and although there are slight modifications each year with the design, the overall shoe is reliable.

Given their innovative designs, a little more could have been invested in the look of the 14+. It looks and feels cheap.

Despite the look, the comfort is unmatched and allows for use in the gym for lifting weights, cardio or running outside.

I have bought Nike Triax shoes for several years and have trained in them successfully for lots of road races including half marathons. When I bought this version, I found it a smidge too small on my bigger foot in the 11, which has always fit me before. I had to trade them in at the store for a different brand.

Took them out for their first little 3 mile test run and they are great so far. Usually if something is good right out of the box, it will work for me. I had worn Structures before but not for a few years. Tried on the previous edition but it didn't fit me right. This one probably runs a bit smaller, but has a nice wide toe box, which I need.

I run about 4 miles about 4 times a week. Mostly on pavement, sometimes on the golf course. This shoe is one you just forget you have on. Fits better than most Niki's -- plenty of room for toes and nice feel on the heel.

I run half marathons and am on my 5 or 6th pair of triax shoes. They hold up well. Have good cushioning. I train on pavement, trails & sometimes treadmill & i dont have problems with foot, shin or knee pain

Been using the ZoomStructureTriax for the last 3 years because of serious ITB syndrome. The stability is fantastic and has helped me get over the pain throughout the years. This upgrade has great cushioning and support, noticeably better than previous years. My only complaint was that I couldn't get it in the hot pink color of my old version!

I absolutely love the Nike Structure Triax. I've been wearing them to run since my very first tri in 2003! Every few years, I go back to the running store to get fit for new shoes and they always put me back in the structure triax. This is a GREAT shoe if you over pronate. It does wear out quickly though. I have to replace them every 3-4 months. I can always feel it in my hip when it's time for a new pair. I'm actually not sure if that's particularly fast, but it's well before 500 miles.

These are great looking shoes, but are very stiff. Have had them for a few weeks now and still don't feel very broken in. Had the previous structure 13 model and these just don't compare. However they do provide a lot of support (use them in spin and step class). Not bad, 13 model was better.

The staff on the phone was very knowledgeable and helpful. I called twice before placing an order and both people did a great job of comparing and contrasting the shoes I was considering. I have never had shoe sales people in other stores know the shoes like the people at RRS, both in the store and on the phone.

I bought these for my wife who just started running and has been unable to find a pair of running shoes right for her feet. This is the first pair that she has put on her feet where she is comfortable.

This was a brand change for me after more than 10 years. My husband is a Nike convert so I agreed to test this "newcomer'"I am now in the Triax camp as this shoe is a great "Lightweight Mate" for my regular runs.

I have had roll issues in the past and that was a concern but I need not have questioned this upgraded Triax - I am now in the Nike Triax camp.
